| Always start with the homozygous recessive. In this case green scales (bb)
The homozygous recessive will be q2, so
q2 = 0.25
You can work out what q is from square root of 0.25
Remember that p+q = 1.
Put the value of q into that equation and you can work out what p is and hence what p2, and 2pq !!
